The project is a new build community hospital for Gloucestershire Healthand Care Foundation Trust. The new facility includes a Minor Injuries unit withseparate adult and children waiting areas, x-ray, radiology and ultrasoundservices, consulting and treatment rooms for outpatient clinics, a children’sclinic area, endoscopy suite and clinic space for dentistry and podiatry.
Following a 1st stage tender period, Dodd Group were selected to reviewthe current proposed stage 2 design. Dodd Group engaged Hoare Lea as designpartners, to develop the project design to stage 3 incorporating valueengineering measures throughout the scheme whilst still maintaining thefundamentals of the Client Brief. A revised MEP servicing strategy wasdeveloped through the process in conjunction with strategic design workshopsand reviews with the Trust to ensure their key requirements were met whilstrationalising the servicing strategy to achieve savings from the original stage 2 design budget.
The revised design scheme utilises ASHP units for both heating and hotwater. The internal spaces being served by LTHW underfloor heating and centralAHU air systems to the individual spaces. This solution significantly reducedthe initial capital cost in lieu of the traditional LTHW radiant panelsstrategies normally specified within healthcare areas contributing towards thefinal build cost. The current design also includes 1000kVA transformerin the barn and the LV cable will be ducted into the building feeding the mainLV switchgear in the roof enclosed plant room. A split LV switchboard(Essential and Non-essential) will be provided in the roof enclosed plant room.Separation will be provided such that a single fault or single incident on oneside of the panel could not cause damage to the other side. The two sides will be connected bymeans of a bus coupler, during normal operation this link will be live allowingboth sides to be fed from the primary supply. In the event of power failure anautomatic breaker will open separating the essential side of the switchgearallowing it to be fed via the generator.
The developing stage 3 and 4 designs were re-measured throughout theprocess to give all parties cost indication at each stage on the budget to worktowards the final GMP cost and Stage 4 design Contractor’s proposals pack andderogation schedule which was signed off by all stakeholders prior tocontractual close.
Offsite fabrication is being used where possible in the form of main pumpand pressurisation plant skids for the heating systems, fabricated LVdistribution panels and earthing terminals. Specialist medical trunkingassemblies were manufactured off site incorporating all specialists final fixinstallations only requiring fixing and final connections at the head of theunits for time efficiency.
The goal of the scheme is to achieve and deliver a low carbon solutionwhich delivers on the UK’s Net Zero Carbon targets. Given this, we utilised LZCtechnologies with Air Source Heat Pumps heating and hot water, CentralMechanical Ventilation, High efficiency VRV systems for comfort cooling andSolar PV, whilst working within the HTM and HBN guidelines.
